Rock or Bust, the group embarked on a seventeen-month world tour. Prior to the tour, drummer
Phil Rudd was charged with attempting to procure murder, threatening to kill, and possession of
methamphetamine and
cannabis. For the tour, Rudd was replaced by
Chris Slade, who had also previously played with AC/DC on their 1990 album
The Razors Edge, several years after Rudd first left the band. By 2016, lead singer
Brian Johnson had started to suffer hearing loss, causing the final ten dates of the
Rock or Bust tour to be rescheduled. Ultimately, he was replaced with
Guns N' Roses vocalist
Axl Rose for the remaining dates. On 8 July 2016, bassist
Cliff Williams announced that he would be retiring from the band once the tour was finished, citing health issues as reasons for retiring, and calling AC/DC a "changed animal".

Bryan Adams, suggesting the band were working where they had recorded their three previous albums. The rumours were later confirmed as the truth, with the album having been recorded there over a six-week period in August and September 2018 with producer
Brendan O'Brien, who also oversaw 2008's
Black Ice and 2014's
Rock or Bust, with some tweaking having followed in Los Angeles in 2019. Every track is credited to Angus and Malcolm Young as Angus had raided the AC/DC vault of unreleased songs to record the album.
